You are only entitled to submit a dissertation to the Department of Biology, Chemistry, Pharmacy once you have been admitted. For externally supervised students, this is also linked to the necessary commitment of a professor from our department, whose primary employment is with the university, as a second reviewer; capacities are generally limited here. If you do not fulfil the admission requirements according to § 3 of the doctoral regulations, in many cases conditions must still be fulfilled, such as attendance of courses, knowledge level examinations, etc., for which it is again necessary that there is still a corresponding remaining period of the standard time to completion.
